CLOSET.

SPECIFICATION forming part of Letters Patent No. 365,937, dated July 5,1887.

. Application filed March 12, 1887. Serial No. 230,688. (No model.)

To all whom it may concern:

Be it known that I, JOHN PARK, of Detroit, county of Wayne, State ofMichigan, have invented new and useful Improvements in ater-Closets; andI declare the following to be a full, clear, and exact description ofthe same, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form a part of this specification.

My invention consists of the combination of devices and applianceshereinafter specified, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a sectional view of a water-closetembodying my improvements. Fig. 2 is a plan view of the same. Fig. 3 isa separate view of the flushing-valve in section; Fig. 4:, a sideelevation of the top of same.

My invention relates more particularly to the peculiar construction andrelation of the ventilating-flue for ventilating both the bowl and thewater-tank; also, to a peculiar construction of lift-valve mechanism,whereby it serves at the same time as an overflow and a stench-trap forsaid overflow; also, in apeculiar construction of the flushing-valve.

In carrying out my invention, A represents the bowl, B the water-tank,and O the exit conduit, of a watercloset. D is its lift-valve mechanism,E its float, and F its flushing valve mechanism. G is itsventilating-flue. The lift-valve mechanism consists of a rubber ring orother suitable valve,- D. This is secured to the bottom of a tube, D. Atthe top of the tube is a bridge, D, to which is engaged the lifting-rodD.

D is a plate or valve attached to the lower end of the rod (2. This rodpasses through a suitable guide, (2', at its lower end, audits upper endpasses freely into the liftingrod D. A spring, (1, upon the rod (1,rests upon the guide (1, and beneath a stationary collar, (1 on the saidrod (1 This plate or valve D is preferably of soft metal, although itmay be of rubber or other material, and seats snugly up against theedged, which constitutes the valveseat. This edge (I may be of brass orof any other suitable material, and I prefer to make it in the nature ofa bushing, so that it may,

if desired, be made of different metal from the lift-tube D, and can berenewed if necessary.

It is apparent now that should the flushvalve or float be out of orderand an excess of water flow into thetank or bowl it cannot rise higherthan the top of the tube D, for it will then pass into the tube, and assoon as the column rises to a small height in the tube its weight willdepress the spring (1, the valve D will open, and the excess of waterwill pass through below. As soon as the water has ceased to flow in thebowl or tank and the column has partly wasted from the tube D the spring(1 will act to lift the valve D and cause it to seat snugly upon itsseat (I, thus preventing a backflow of stench or sewer gases andeffectually securing the same with a water seal.

The flushingvalve mechanism consists of a duit, F leading by means ofthe flushingpassage to the rim of the bowl in the usual way.

Another compartment, F beneath, communicates freely with thewater-supply pipe F Upon the under side of the dividing-partitlon is adepending edge, f, which constitutes the seat for the valve F. Thisvalve is fastened securely to the stem f, and is preferably providedwith a block of rubber, f or soft metal or other suitable material. Aspring, f, beneath the valve operates in a direction to assist the,water to seat the valve and to hold the valve-stem firmly against thefloat-arm until the valve finally reaches its seat. This has the effectto cause the valve to seat quietly and not with a jump, as is quitefrequent. The valvestem is engaged with the float-arm by a slotand-pinconnection, f, so as to admit of sufficient play to avoid any bindingbetween the parts or upon the line of the valve-stem.

It will be observed that this valve has no packing of any kind and thatits parts are exceedingly simple and accessible.

It has been customary to ventilate both the bowl and the water-tankeither by separate connections with a chimney or special fine or byconnecting the bowl with the tank by a passage and then connecting thetank alone with said flue. In this latter case the connection hasusually been at the extreme rear of the tank and quite inaccessible inthe large macase, F. A compartment, F, has an eXit-conjority of caseswhere the closet is set closely back against a wall. To avoid this I-connect the bowl and tank by a connecting-passage, G, and then leadingoff a connection from this passage, as shown at G, to the ventilatingfine or chimney. This passage G is located well forward between the tankand bowl', so that no matter where the closet may be set this connectionwill always be readily accessible to the plumber.

What I claim is- 1. The combination, in a water-closet, ofthe bowl A,the tank B, having its lower portion in direct communication with thedischarge of the bowl and joined thereto, the lift-Valve D, having thetube D provided at its upper portion with a bridge, D, and at its lowerportion with a bridge, (1", the tubular lifting-rod D", connected withsaid bridge, a trappingvalve, D arranged at thelower end of the tube andprovided with a valve-rod, (1 extending up through the said bridges intothe tubular lifting-rod and movable vertically therein, and a spring, d,on the valve-rod, substantiall y as described.

2. The combination, with the water-closet bowl A and the water-tank B,communicating therewith, 'of the flushing-valve mechanism, consisting ofthe twocOmpartment case F F, having the valve-seat f, the valve-stem f,having the upwardly-seating valve F and extending through the top of thecase, the spring f, the float E, and the pivoted float-arm earrying thefloat and having a pin-connection with the upper end of the valve-stem,whereby the float aids in closing the valve, substantsally as described.

In testimony whereof I sign this specification in the presence of twowitnesses.

JOHN PARK.
